Description

Technical Field

[0001] The utility model relates to the technical field of cable branch boxes, in particular to a cable branch box. Background Art

[0002] Cable branch boxes are equipment used for the wiring, distribution and protection of cables. They usually contain multiple cable branching units, each of which is designed to connect and distribute cables. Cable branch boxes are widely used in power systems, industrial facilities and buildings to effectively manage and distribute cables, as well as provide corresponding electrical protection.

[0003] The cable branch box in the prior art is usually provided with heat dissipation holes for heat dissipation. However, in windy and rainy weather, rainwater is easily blown sideways into the cable branch box by the strong wind. After long-term rainfall, some rainwater is easily accumulated in the cable branch box, causing damage to the internal electrical components, posing a safety hazard.

[0004] Therefore, a cable branch box is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a cable branch box to solve the problem that rainwater falls sideways into the cable branch box in windy and rainy weather, causing damage to the internal electrical components.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a cable branch box, comprising a box body with a heat dissipation hole one, an installation room is arranged in the box body, a plurality of heat dissipation holes two are symmetrically arranged on the two outer side walls of the installation room, and a heat dissipation port is arranged on the top surface of the installation room, rain shield components are symmetrically arranged on the side walls of the installation room with the heat dissipation holes two, the rain shield components completely cover the heat dissipation holes two when closed, and contact with the inner circumferential wall of the box body when opened, a drainage component is also arranged in the box body directly below the installation room, a plurality of drainage holes are arranged on the lower end of the outer circumferential wall of the box body, and the drainage component reciprocates along the direction of the drainage holes.

[0007] By adopting the above technical scheme, the installation room is used to install various electrical components. The heat dissipation hole 2 opened on the side wall of the installation room allows the generated heat to be discharged from both sides of the installation room and then discharged to the outside through the heat dissipation hole 1. The heat dissipation port further improves the heat dissipation and ventilation effect in the installation room. When the rain sensor detects that the rainfall is too heavy, it controls the rain shield component and the drainage component. The rain shield component can completely cover the heat dissipation hole 2 when it rains to prevent rainwater from entering the installation room from the heat dissipation hole 2 and causing damage to the electrical components. After blocking the heat dissipation hole, heat can be dissipated through the heat dissipation port without affecting its heat dissipation effect. On non-rainy days, the rain shield component will not block the heat dissipation hole 2, so that the heat discharged from the heat dissipation hole 2 can be smoothly discharged to the outside. At the same time, when rainwater enters the box from the heat dissipation hole 1, the drainage component at the bottom of the box can discharge the rainwater from the bottom of the box to prevent rainwater from accumulating at the bottom of the box.

[0008] The utility model is further configured as follows: the rain shield assembly includes a rain shield plate 1, a rain shield plate 2, a rotating rod 1, a rotating rod 2 and a motor 1; the rotating rod 1 is rotatably connected to the upper end of the outer peripheral wall of the installation room; one side of the rain shield plate 1 is fixedly connected to the rotating rod 1; the motor 1 is fixedly connected to the side wall of the installation room, and the output end of the motor 1 is transmission-connected to the rotating rod 1; the rotating rod 2 is rotatably connected to the lower end of the outer peripheral wall of the installation room; the end of the rotating rod 1 away from the motor 1 is fixedly connected to the pulley 1; one end of the rotating rod 2 is fixedly connected to the pulley 2; a synchronous belt is arranged between the pulley 1 and the pulley 2.

[0010] The utility model is further configured as follows: when the first rain shield and the second rain shield are in contact with the outer peripheral wall of the installation room, the projection surface of the heat dissipation hole 2 falls on the projection surface of the first rain shield and the second rain shield.

[0011] By adopting the above technical solution, it is ensured that the rain shield 1 and the rain shield 2 can completely cover the heat dissipation hole 2 to prevent rainwater from entering the installation room.

[0012] The utility model is further configured as follows: electromagnets are arranged at the contact ends between the first rain shield plate and the second rain shield plate and the inner peripheral wall of the box body.

[0013] By adopting the above technical solution, one end of the first rain shield and the second rain shield can be fixed to the inner wall of the box body when it is not raining.

[0014] The utility model is further configured as follows: the first rain shield is provided with a first water guide groove, the second rain shield is provided with a second water guide groove, and the first water guide groove is communicated with the second water guide groove.

[0015] By adopting the above technical solution, when rainwater enters the box from the heat dissipation hole 1 and falls sideways on the rain shield, the rainwater can flow downward along the water guide groove 1 and the water guide groove 2 and fall to the bottom of the inner peripheral wall of the box.

The two sliders are slidably connected to the side walls of the mounting plate, and the side walls of the two sliders are rotationally connected to the transmission rod. The end of the transmission rod away from the slider is rotationally connected to the drainage plate in contact with the bottom surface of the inner peripheral wall of the box body, and the two sliders are respectively threadedly connected to the positive and negative threads on the surface of the bidirectional screw.

[0017] By adopting the above technical solution, the drainage plate can reciprocate to discharge the rainwater accumulated at the bottom of the box body out of the box body through the drainage holes.

[0018] The utility model is further configured such that: when the sliding block is at the maximum stroke position, the drainage plate contacts the inner peripheral wall of the box body.

[0019] By adopting the above technical solution, it is ensured that the drain board can smoothly discharge the accumulated water out of the box.

On non-rainy days, the rain shield component will not block the heat dissipation hole 2, so that the heat discharged from the heat dissipation hole 2 can be smoothly discharged to the outside. At the same time, when rainwater enters the box from the heat dissipation hole 1, the drainage component at the bottom of the box can discharge the rainwater from the bottom of the box, so as to prevent rainwater from accumulating at the bottom of the box.

[0029] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] Example:

[0031] like Figures 1 to 4As shown, a cable branch box includes a box body 11 with a circular heat dissipation hole 12, a rain sensor 13 is arranged on the top surface of the box body 11, and when excessive rainfall is detected, the cable branch box controls the rain shield component and the drainage component to start working, and the heat dissipation holes 12 are arranged in an upper, middle and lower linear array on the outer peripheral wall of the box body 11, and the hot air generated in the box body 11 can be discharged from the heat dissipation holes 12, and an installation room 14 is arranged in the box body 11, and the two outer side walls of the installation room 14 are symmetrically provided with heat dissipation holes 15, and the heat dissipation holes 15 are provided in two rows for discharging the heat in the installation room 14, and the top surface of the installation room 14 is provided with a heat dissipation port 16 to enhance the heat dissipation effect of the installation room 14, and the side walls of the installation room 14 with the heat dissipation holes 15 are symmetrically provided with rain shield components, which completely cover the heat dissipation holes 15 when closed, and the rain shield components When open, it contacts the inner wall of the box body 11. The rain shield component can completely cover the heat dissipation hole 2 15 when it rains, preventing rainwater from entering the installation chamber 14 from the heat dissipation hole 2 15 and causing damage to the electrical components. After blocking the heat dissipation holes, heat can be dissipated through the heat dissipation port 16, which will not affect the heat dissipation effect. On non-rainy days, the rain shield component will not block the heat dissipation hole 2 15, so that the heat discharged from the heat dissipation hole 2 15 can be discharged to the outside through the heat dissipation hole 12. A drainage component is also provided in the box body 11, which is located directly below the installation chamber 14. A plurality of drainage holes 17 are opened at the lower end of the outer wall of the box body 11, and the drainage component reciprocates along the direction in which the drainage holes 17 are opened. When rainwater enters the box body 11 from the heat dissipation hole 12, the drainage component at the bottom of the box body 11 can discharge the rainwater from the bottom of the box body 11, preventing rainwater from accumulating at the bottom of the box body 11.

[0032] like Figures 1 to 3As shown, there are two groups of rain shield components, wherein the rain shield components include a rain shield 18, a rain shield 2 19, a rotating rod 1 20, a rotating rod 21 and a motor 1 22. The rain shield 1 18 and the rain shield 2 19 are plate-like structures made of stainless steel material, and the outer dimensions of the rain shield 18 and the rain shield 2 19 are the same. The rotating rod 1 20 and the rotating rod 21 are both cylindrical rod-like structures, and the sizes of the two are the same. The rotating rod 1 20 is rotatably connected to the upper end of the outer peripheral wall of the installation chamber 14, one side of the rain shield 18 is fixedly connected to the rotating rod 1 20, the motor 1 22 is fixedly connected to the side wall of the installation chamber 14 with bolts, and the motor 1 The output end of the motor 22 is connected to the rotating rod 20 for transmission. When the motor 22 is started, the output end drives the rotating rod 20 to rotate, and the rotating rod 20 further drives the rain shield 18 to rotate. When it rains, the rain shield can be controlled to block the heat dissipation hole 215 to prevent rainwater from entering the installation room 14. The rotating rod 21 is rotatably connected to the lower end of the outer peripheral wall of the installation room 14. The end of the rotating rod 20 away from the motor 22 is equipped with a pulley 23, and the end of the rotating rod 21 is equipped with a pulley 24. A synchronous belt 25 is arranged between the pulley 123 and the pulley 24. When the pulley 23 rotates, the pulley 24 is driven by the synchronous belt 25. The motor 1 22 is driven by the rain shield 1 18 and the rain shield 19 to rotate together, thereby controlling the rotation of the rotating rod 21 to drive the rain shield 19 to rotate together. When the motor 1 22 is started, the rain shield 1 18 and the rain shield 19 can be controlled to rotate at the same time to cover the heat dissipation hole 2 15 to prevent rainwater from entering the installation room 14. When the rain shield 1 18 and the rain shield 19 are in contact with the outer peripheral wall of the installation room 14, the projection surface of the heat dissipation hole 2 15 falls on the projection surface of the rain shield 1 18 and the rain shield 19, ensuring that the rain shield 1 18 and the rain shield 19 can completely cover the heat dissipation hole 2 15 to prevent part of the rainwater from leaking into the installation room 14. The rain shield 1 18 and the rain shield 19 are in contact with the inner peripheral wall of the box body 11. An electromagnet is provided at the contact end, and one end of the rain shield 18 and the rain shield 2 19 can be fixed on the inner wall of the box body 11 when it is not raining. The rain shield 18 is provided with a long strip of water guide groove 16, and the rain shield 2 19 is provided with a long strip of water guide groove 27. When the rain shield 18 and the rain shield 2 19 cover the heat dissipation hole 2 15, the water guide groove 1 26 and the water guide groove 2 27 are connected. When rainwater enters the box body 11 from the heat dissipation hole 12 and falls sideways on the rain shield, the rainwater can flow downward along the water guide groove 1 26 and the water guide groove 2 27 and fall to the bottom of the inner wall of the box body 11, so that the rainwater will not accumulate on the rain shield.

[0033] like Figure 1 to Figure 2As shown, there are two groups of drainage components, and the drainage components include a bidirectional screw, two sliders 29, a transmission rod 30 and a drainage plate 31. The lower end of the inner wall of the box body 11 is fixed with a motor 32 by bolts, and the output end of the motor 32 is connected to the bidirectional screw. A rectangular plate-shaped mounting plate 34 is welded to the bottom surface of the inner wall of the box body 11. The two sliders 29 are slidably connected to the side walls of the mounting plate 34. The mounting plate 34 allows the sliders 29 to move in the horizontal direction, and the side walls of the two sliders 29 are rotatably connected to the transmission rod 3 0, one end of the transmission rod 30 away from the slider 29 is rotatably connected to a drainage plate 31 in contact with the bottom surface of the inner wall of the box body 11, and the two sliders 29 are respectively threadedly connected to the positive and negative threads on the surface of the two-way screw. When rainwater accumulates at the bottom of the box body 11, the motor 2 32 is started and the two sliders 29 are driven to move toward the center of the two-way screw through the two-way screw, and then the drainage plate 31 is driven forward through the two transmission rods 30, so that the rainwater accumulated at the bottom of the box body 11 is pushed to the drainage hole 17 by the drainage plate 31 and then the accumulated water is discharged.

[0034] When the cable branch box is working, when the rain detector detects that the rainfall is too heavy, it sends data to the controller of the cable branch box. After the controller controls the motor 22 to start, the rain shield 18 and the rain shield 2 19 rotate at the same time and cover the heat dissipation hole 2 15 to prevent rainwater from entering. At the same time, the heat generated in the installation room 14 can be discharged through the heat dissipation port 16 of the installation room 14. The heat dissipation fan 33 can further improve the heat dissipation efficiency, so that the cable branch box has a rainproof effect while not affecting the internal heat dissipation. When rainwater falls into the box body 11 from the side of the heat dissipation hole 12, the rainwater dripping from the rain shield 18 and the rain shield 2 19 and other rainwater that falls in accumulate at the bottom of the box body 11, the motor 2 32 starts and the drainage component starts to work. The drainage of the drainage component reciprocates in the direction of the opening of the drainage hole 17, and the accumulated rainwater is discharged from the box body 11 through the drainage hole 17.
